IMPROVEMENT IN CULTIVATQRS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that l, H. MURTIN Rosaof Clinton, in the county of De Kalb and State of Illinois, have 'invented a new and improved Cultivator; and' I-do Figure 2, sheet 2,- is a central longitudinal section v of the same.

Figure3, sheet 2, is a detached sectional view of' parts to be hereinafter referred to.

Similar letters of reference indicate -corresponding parts in the several figures of the drawing,

My invention has for its object to improve the construct-ion of cultivators, whereby the same are rendered more eicient in their operation.

The invention consists- First, in constructing the tongue with a bifurcated end attached to the axle, to receive the seat-arms andl permit an unobstructed view of the plants from the driveis seat during cultivation.

It also consists in the provision of means for adjusting the drivers seat upon the seat-arms for the purpose of adapting the former to the most convenient and easy positions for the driver.

It also consists in suspendingl the operating parts of a cult-ivator beneath the axle from a frame whichis mounted upon said axle by means of pivoted adjustable bars, whereby the plow-beamsl are allowed an increased lateral play and adjustment-andan increased vertical movement when the plows are raised out ot' the ground, and whereby the parts are adapted for operation with the utmost case and eiciency.

It also consists in the combination of the various parts by which these results are obtained. y

It also consists in the provisionof means for accommodating the angle of the framesl vwhich guide the plow-beams to the various adjustments of the plows between the rows ot' plants tobe cultivated, whereby the plow-beams are 'permitted a free'and easy vertical play within the frames without binding.

It also consists in the provision et' means for adjusting the position ofthe plows to throw the dirt -nearer to or farther from the plants during cultivation. Y

lt also consists in the construction and operation of the foot-levers and horns by which thc plows are operated and thrown out of operation by the feet ofthe driver.

It also consists in the method of connecting the front ends ot' the plow-beams to the draft-pole, to per# mit their vertical and lateral play.

In the accompanying drawing- A is the bent axle, supported upon wheels B in the usual manner. Each bend of the axle, instead of forming an angle, is made to describe the are of a circle, for the purpose ot' preventing the liber of the iron from being broken, and thereby weakening the axle.

C is the tongue or draft-pole, having its `rear end bifurcated and secured to the upper side of the axle by means of metallic eyes and nuts (Z, or by any other suitable means.

E is a quadraugular or rectangular frame, rising above the axle and inclined somewhat toward the'rear ofthe machine.

It is'supported upon the axle immediately within the wheels, and is braced from the tongue by short bars or rods F. v i

The upper or cross-bar G of this frame is provided with vertical slots, in which the upper ends of the bent metallic bars H are adjustably suspended by any suitable jointed or iiexible connection.

As the frame E is inclined somewhat to the rear of the machine,the bent `barslEI drop behind the axle, and are pivoted at their lower .ends to the lower ends 4of small rectangularfwooden frames, I, placed in up'- right4 positions for the reception of the plow-beams, and whoseupper ends -are suspended from a horizontal slotted bar or beam, J, in the following manner:

K are short loops or slatted bars placed upon'the frontvside of the bar J, at each end, and provided with bolts l, which pass laterally through slots m formed in the ends of the bar J, and are secured to the frame J by means of burs n, as shown.

By this arrangement the rectangular plow-beam frames are suspended from the cross-bar ofthe frame E, but held iu an upriglit position by means of lthe horizontal bar J. The loops K permit thelateral play of the frames I, sc that the plows may be guided nearer to or farther from the plants to be cultivated.

N are the plow-beams, 'passing through the rectangular ii'ames I, and extending in converging line's to the front of themachinc, where they arel secured to a block, o, upon the under side ofthe draft-pole in front of the bifurcation 'of the latter.

This block is provided with two short arms, 11,10 which the plow-beamsA are connected by means of metallic plates,.q, in such a manner as to permit of ready verticall movement, while the block itself is pivoted to the underside of the-pole to admit of the lateral motion of the plow-'beams when the plows are in operation. Y

The plates q are so connected to the pivoted blocks and piety-beams as to permit tile lateral adj nstment of the plows to accommodate the varying distances between the rows of plants to be cultivated.

Inasmuch as the angle described by the forward ends of the plow-beams varies in proportion to the adjustment of the plows between the rows of plants, it is necessary that the rectangular frames I be placed laterally at such an angle upon the bar J as to permit the vertical play of the plow-beams without binding between the side bars of said frame.

To accomplish this result'wedges fr are introduced between the upper ends of the frames and the bar J.

S are braces extending from the proximate sides of the frames I to about the center of the bar J, where they are secured, by bolts and nuts, within slots f, formed in said bar.

To effect the lateral adjustment of the plows, the frames-.I and loops Kare moved upon the bar J by loosening the bolts I, the braces S being also adjusted at the same time.

Thependent bars.H..a1ealso.adjustedvnpon the/ frame E to admit of the full lateral play ofthe plows, or, in other words, to allow the bars to move 1through the entire length of the loops K, and thus permit th full lateral play ofthe plows.

T are-the plows, aixed to standards U in the usual manner.

The upper ends of the standards are secured to the plow-beams by means of the eye-bolts V and -nuts W, shown in fig. 3.

Between the beams and the standards ot' each plow a beveled recessed block, X, is placed, through which the shank of the eye-bolt passes. v

The inclination of this block, as it is turned upon the eye-bolt, adjusts the angle given to the plow to throw the dirt nearer to or farther from the plants.

The recess upon its face serves to prevent the eye ofthe bolt fronropening and allowing the standard to dropout. This would be the result without the recessed block, from the fact that the eye, in order to save the expense and labor of welding, isznot formed continuously upon the bolt, but by bending the latter upon itself and leaving the bent end disconnected from the main portion, as shown at y, fig. 3.

The plow-standards are braced from the beams by means of the braces Z in the usual manner.

To prevent the guide-frames I from moving forward toward the axle, blocks A are secured to the plow-beams in front of the frames.

Friction-wheels may be substituted for the blocks, if desired, to prevent the frames from obstructing the play of the plow-beams.

B is the drivers seat, and

G are the arms by which the same is supported upon the machine.

v These arms are formed of a single piece of metal, doubled upon itself in such a 'manner as to receive between them, at the -point of bending, the block D, which is irmly secured to the under side of the seat.

This block is pivoted .at its rear ,end between the arms, and its forward end is slotted for the passage of a bolt, e', by which means the position of the seat is adjusted for the comfort and convenience of the driver.

The seat-arms C extend along the proximate surfaces o'f the draft-pole arms, passing through loops f affixed to the latter, and their forward ends are bent upward and downward to form segmental guides, which pass through loops or staples g secured to the draftpole.

By moving these segmental guide-arms up or down wit-hin the staples the position of the seat with relation to the plows is adjusted.

The seat-arms are adapted for adjustment longitudinally upon the draft-pole to balance the frame of the machine upon the axle'l under the weight of the driver.

Thisis accon'iplished by shifting tlhe'staples g into one or the other of the series 'ot' holes h. formed in the draft-pole arms, and sliding the Seat-arms through the loops j" to correspond thereto.

By this arrangement of the seat-arms and draftpole the driver is permit-ted an unobstructed view, between the plows, of the plants to be cultivated.

If preferable the seat-arms may be formed of two pieces of metal instead of one piece, bolted or otherwise secured together to receive the seat-block.

I are horns a'ixed to the outside of the plowbeams, within reach of the drivers feet, whereby he 'is enabled to guide the plows during the operation of cultivating.

The shanks of the horns are notched upon one edge to catch upon staples aiiixed to the plow-beams, and are held in place by keys j, as shown.

By this means the horns are adapted for vertical adjustment, so thatthey mayat Yall times lieavithint er Y Y e reach of the drivers feet.

K are the levers, by which the plow-beams are raised to lift the plows out of the ground.

They are each constructed in two parts, and pivoted to the proximate sides of the guide-frames I by means of the. bolts which connect the braces S to 'said frame-s.

The under part t" is provided with a frictionroller, m', extending under the plow-bea m, and the .part n' with a foot-rest, o', and with a lateral pin which is adapted to engage with a perforated segmentnpon the rear end of the part By'changing this pin into one or the other of the holes in the segment the foot-rest` is brought within reach of the drivers foot.

The rollers fm.' are designed to reduce the friction upon the plow-beams when the levers are depressed to lift the plows ont of the ground.

The plow-beams, are suspended within the guideframes by means of looped chains P', which admit of the beams being raised, b ut prevent their dropping down too far within the frames.

Q' are braces extending from the draft-pole to the short plates R'npon the bottom of the nprights of frame E, and serve to hold the draft-pole more firmly in place upon the axle. v

S is' the draft-bar, pivote-d to the under side of thc tongue, or to a block, T', secured to the latter, andl is provided at its end with the pivoted pendent bars U', to which the whitle-tree hooks V are.

attached.

W are draft-rods hinged to the pendent bars, between their upper ends and the hooks V, and also hinged at their opposite ends to the plates R'.

By this -construction a jointed ldraft-bar is produced which not only equalizes the draft of the team, but carries the line ot' draft below the tongue and nearer to the plows.

The pendent bars swing upon their pivots and their lower ends are drawn forward and back, according to the draft 'of the team.

Havingthus described my invention,
